Her obsession with the then wholesome singer grew and she listened to her music every day, mastering her singing voice and southern American accent.

In 2008, after years of constant comparisons by friends and family, Jessica decided to send some photographs to a lookalike agency who signed her up as an official Miley impersonator.

Since then, the pint sized teen has been hired to perform at birthday parties and events all over the world, entertaining fans with crazy tongue wagging and booty shaking performances - belting out Miley's latest hits.

"I love how confident she is, she doesn't care what people think of her and that's so inspiring. Young girls need a good role model and I think she's perfect. She's not pretending to be someone she's not, and I admire her for that," she says.

The Wrecking Ball singer has faced a barrage of criticism for her sexy on stage antics and pro-drugs message, but Jessica refutes the idea that the 21-year-old star is corrupting her young fans.

"Miley is an adult now. A lot of people still think she's Hannah Montana- the Disney star. She's not, she's Miley Cyrus - the pop-star," said Jessica.

"I don't think she is a bad influence, not at all, it's just a stage act. People who criticise her are just jealous."

Jessica, who lives at home with parents, Johana, 39, Enrique, 42 and brother Henry, 16, even managed to gate-crash a celebrity event by fooling bouncers that she was the real deal.

And after talking her way into the bash Jessica received a phone call from Miley's promotions manager and was invited to work as an official lookalike for the racy starlet.

But her looks can also cause her some problems. And the teen, who spent £200 transforming her long brown tresses into a bright blonde crop, once drew a crowd of 3,000 Miley fans, desperate for an autograph and picture with their idol.

"They were so convinced I was the real deal. I was signing autographs for little girls who were screaming in excitement - thinking I was her," said Jessica.

The part-time waitress, who had never seen the star perform live, has also been mobbed in the street and had people sneaking pictures of her on their phones.

In fact in March, while Jessica was enjoying a music festival with her family in Tennessee, US, she was forced to hide in her car as crowds gathered for a glimpse of the "twerk out" star.

"It was really crazy. People were swarming around the car, trying to take pictures of me on their phones," she said. "It was a little scary, but exciting."
